Most properties (skill point color) lack a proper way to enable/disable them

There might be a simple fix for this, but I'm also thinking this is indicative that we need to disengtangle the itemstack logic.

Is this still an issue (that we want to fix)? What do you think @magicus?

It is phrased based on the previous architecture. If there still is a problem, it needs to be described in what needs changing right now. Item rarity color can e.g. be selected by the user.
